You turn on the high beams and they only stay on for five minutes then shut completely off. The lights go out completely.

It sounds like the headlight switch is going out, but to be sure here is a guide to show you how to check for power coming out of the switch to confirm the failure:

Check out the diagrams (below). Please run some tests and get back to us.
